Question

Numerous studies have found that males report higher
self-esteem than females, especially for adolescents
(Kling, Hyde, Showers, & Buswell, 1999). Typical
results show a mean self-esteem score of M  39.0 with
SS  60.2 for a sample of n  10 male adolescents and
a mean of M  35.4 with SS  69.4 for a sample of
n  10 female adolescents.
a. Do the results indicate that self-esteem is
significantly higher for males? Use a one-tailed
test with   .01.
b. Use the data to make a 95% confidence interval
estimate of the mean difference in self-esteem
between male and female adolescents.
c. Write a sentence demonstrating how the results
from the hypothesis test and the confidence interval
would appear in a research report.
